2 Claims.

This invention relates to certain new and useful improvements inhydraulic drain cleaners and the like.

The primary object of the invention is to provide a hydraulic draincleaner wherein a vacuum or suction cup has a forced water supply linecommunicating therewith and opening therein in a manner to create apartial vacuum in the cup when the latter is engaged with the surfacesurrounding a drain opening or the like to effect pulsations in a drainsimilar to a pump action to effect removal of obstructions from thedrain for cleaning the latter and permitting unobstructed flow of waterthrough the vacuum cup and drain.

More specifically, the present invention resides in the provision of aparticular type of water jet nozzle associated with the vacuum cup tocreate a forced ow of waterin fine stream or jet form through the cupfor effectively opening a clogged drain or the like.

With the above and other objects in View that will become apparent asthe nature of the invention is better understood, the same consists inthe novel form, combination and arrangement of parts hereinafter morefully described, shown in the accompanying drawing and claimed.

In the drawing:-

Figure 1 is a side elevational view of a hydraulic drain cleanerconstructed in accordance with the present invention and showing a hoseextending from a sink or the like to the cleaner;

Figure 2 is a vertical sectional View of the cleaner head or vacuum cupwith the water jet nozzle anchored therein;

Figure 3 is a cross-sectional View taken on line 3 3 of Figure 2; and

Figure 4 is a cross-sectional view taken on line 4 4 of Figure 2.

It is to be understood that the cleaner disclosed herein may be used forthe opening of sink or iioor drains, toilet bowls and conduits ofvarious kinds for removal of clogged substances for cleaning a passage.The cleaner comprises a head or vacuum cup 5 substantially of bell-shapeand of the type usually .employed in hand operated plungers, the cup 5being preferably formed of rubber and embodying a attened circularflange B at its open end with an annularly reduced neck 1 at the otherend thereof for the support of a jet nozzle. The jet nozzle comprises atubular stem 8 having an outwardly directed annular flange 9 at itsupper end. An elongated lip or rib IIJ is disposed interiorly of thetubular stem 8 and extends longitudinally thereof with a ange IIdirected outwardly of the upper end thereof and counter-sunk in theannular flange 9 of the tubular stem as shown in Figures 2 and 3, thelip being permanently anchored in position. One fiat side of the lip orribI is engaged with the wall of the tubular stem 8 and the oppositeside thereof bulges outwardly as shown at I2 for reducing the bore ofthe tubular stem at a point intermediate the ends thereof. The mountingfor the tubular stem 3 of the jet nozzle comprises a bushing I3 in theneck l of the cup 5, the tubular stem being supported in the bushing I3with the annular flange 9 at the upper end of the tubular stem engagedwith an annular flange I4 at the upper end of the bushing. The lower endof the bushing I3 terminates flush with the lower end of the neck 'I andthe anchor means for the lower end of the bushing and tubular stem 8includes a sealing gasket I5 surrounding the tubular stem and engagedwith the lower end of the bushing and adjacent portion of the neck, thegasket I5 being retained in position by the collar I6 mounted upon theinner projecting end of the tubular stem that has its lower endterminating substantially midway the upper and lower ends of the cup 5.

The anchor means for the upper end of the bushing I3 and the watersupply devices asso-Y ciated with the cup include a pipe II engaged withthe upper end of the flange 9 of the tubular stem with a gasket I8interposed therebetween, the locking ring I9 retaining the pipe I'I inposition and being engaged therewith as shown in Figure 2 and having a.flanged lower end 2E? engaged with the adjacent end of the neck l anddisposed beneath the bushing flange I4. A manually operable valve 2I iscarried by the pipe Il to control the ow of water through the cup 5 whena flexible or other hose 22 forms communication between a faucet 23 andthe outer end of the pipe I'I as shown in Figure 1.

The tubular stem 8 of the jet nozzle is placed directly over a drainopening or the like with the open end 6 of the cup 5 intimately engagedwith the surface surrounding the opening and the fine jet of waterprojected through the tubular stem creates a partial vacuum in the cup 5and pulsations in the clogged drain opening in simulation of a pumpaction for clearing the drain opening of any obstructions lodgedtherein. The hose 22 may be of any length desired and the flow of waterthrough the vacuum cup 5 is controlled by the valve 2 I.

While there is herein shown and described the preferred embodiment ofthe invention, it is nevertheless to be understood that minor changesmay be made therein without departing from the spirit and scope of theinvention as claimed.

1. In a hydraulic drain cleaner and the like, a

5 flexible cup of bell-shape having a reduced neck through the tubularstem to increase jet action Y thereof including an elongated ribanchored at its upper end to the tubular stem and having a at sideengaged with the wall of the tubular 15 stem and terminating in spacedrelation to the lower end of the tubular stem and a bulged portionintermediate the ends of the rib extending towards the opposite sideofthe tubular stem.

2. In a hydraulic drain cleaner and the like, a

flexible cup of bell-shape having a reduced neck with an openingtherein, a jet nozzle anchored in the neck opening with the dischargeend thereof terminating in spaced relation to the neck, water supplymeans in communication with the jet nozzle, the jet nozzle includingYa'tubular stem, a bushing interposed between the stem and cup neck,means for anchoring Ythe tubular stem and bushing in the neck, means forrestricting the ow of water through the tubular stem to increase jetaction thereof including an elongated rib anchored at its upper end tothe tubular stem and having a flat side engaged with the wall of thetubular stem and terminating in spaced relation to the lower end of the'tubular stem and a bulged portion intermediate the ends of the ribextending towards the opposite side of the tubular stem.
